Secretary-general of EuroNCAP, Michiel van Ratingen, was scathing in his criticism of Jeep's owner, the Fiat-Chrysler group.

"It is truly disappointing to see a brand-new car being put on sale in 2018 with no autonomous braking system and no lane assistance. It is high time we saw a product from the Fiat-Chrysler group offering safety to rival its competitors."

Fiat-Chrysler says the Wrangler "meets or exceeds federal safety requirements in every market in which it is sold".

The company says the Jeep is designed for demanding off-road driving and that "testing protocols that apply exclusively to urban scenarios may not align with such a vehicle."

Fiat Chrysler Australia says the one-star rating may not apply to local vehicles because they will be available with autonomous emergency braking, which can slam on the brakes if the technology senses an imminent collision.

"The Jeep Wrangler arrives in Australia with a long list of standard and available safety equipment, including front and side airbags, blind-spot monitoring, rear cross-path detection, parking sensors, a rear-view camera and autonomous emergency braking, all of which is paired with the use of high-strength steel in its construction designed to protect the cabin in the case of an accident," a spokeswoman says.

The Wrangler will arrive in Australia in the first quarter of next year. Picture: Supplied.

The company argues that the Jeep is a specialist off-road performance vehicle with features not found on regular vehicles.

"Part of what makes it such an icon, is the fact that its doors, roof and windscreen can be removed or folded down," she says.

Australia's independent crash test body ANCAP says it is working with Fiat Chrysler Australia to determine the safety specification of models to be supplied locally.

"Until the local specifications are confirmed, ANCAP is unable to assess if the European test results and subsequent star rating can be applied to local models," a spokeswoman says.

"The European result is disappointing for a newly designed vehicle, and I'd encourage FCA to use the opportunity to improve the safety result in time for its Australasian launch."

Fiat Chrysler says the Jeep is built using high-strength steel in all critical areas.

"The vehicle offers more than 70 advanced safety and security features," the company says.

"Safety is something we take incredibly seriously, and every other member of our Jeep family of vehicles wears a five-star safety rating with pride, whether they have been crash-tested by ANCAP in Australia or by Euro NCAP."
